OBJECTIVES Oral infections and dental caries are still considered as serious public health problems and inflict a costly burden to health care services around the world and especially in developing countries. MATERIALS AND METHODS In the present study, we evaluated the antibacterial activity of Glycyrrhiza glabra (G. glabra) against oral pathogens by diffusion methods and determined the minim...

In plants, flavonoids play an important role in biological processes. They are involved in UV-scavenging, fertility and disease resistance. Therefore, in this study, we attempted to quantify and characterize phenolic compounds in Aesculus parviflora Walt. leaves and Aesculus glabra leaves partly suffering from attack by a leaf mining insect (C. ohridella). A total of 28 phenolic compounds belon...

Ulmus pumila is considered an invasive tree in 41 of the United States. In this study, we examined the extent of hybridization in naturalized populations of U. pumila, its impact on genetic diversity and genetic structure and its potential role in explaining the invasion process of U. pumila. Genetic analyses indicated widespread hybridization with native Ulmus rubra in naturalized U. pumila po...

Tree seedling flooding tolerance for 22 species was assessed under controlled field condi­ tions. Initial heights under control (freely draining soil, n = 20 per species) and flooded (stand­ ing water, depth = 10 cm, n = 20 per species) conditions were measured in March 1990. Sur­ vival, height and diameter growth were determined after 120 days. Recovery from flooding effects was assessed in th...

Elaeagnus glabra (Thunb.), an evergreen shrub with alternate leaves, has been used as a medicinal plant in Korea. Since many plant-derived molecules have inhibitory effects on tumor cell invasion, primarily via suppression of the activity of matrix metalloproteinases (MMPs), we investigated the effect of the methanol extract of E. glabra on tumor cell invasion. The invasiveness of HT1080 human ...

It had been demonstrated that Glycyrrhiza glabra extract has biological capabilities include detoxication, antioxidation and antiinfection properties, although there is little data available about its probable side effects on the liver integrity. So, the effects of G. glabra administration on the liver ́s histology and some biochemical parameters were investigated in the rats. Thirty-two Sprague...

Objective: The aim of the present study was to assess the anti fungal activity of ethanolic extract of Glycyrrhiza glabra. Glycyrrhiza glabra commonly called as liquorice or sweet root is one of the oldest known herbal remedies famous for its vast variety of therapeutic properties. Ethanolic extract of Glycyrrhiza glabra was tested for antifungal activity against Candida albicans, Aspergillus n...

Five species of Caudinidae occur in New Zealandwaters. Two new species are described: Paracaudina alta sp. nov.; Paracaudina reductia sp. nov. Two species reported previously are discussed: Paracaudina chilensis (Müller) and Paracaudina coriacea (Hutton). A lectotype has been established for P. coriacea (Hutton). Hedingia albicans var. glabra (Théel) is raised out of synonymy with Hedingia albi...

cerato-ulmin is the most important toxin of fungal causal agents of dutch elm disease and its content is one of the most important factors to distinguish two species ophiostoma ulmi and o. novo-ulmi. with attention to the ophiostoma novo-ulmi is more pathogenicity than o. ulmi, this research was carried out to discuss the role of cerato-ulmin on pathogenicity of causal agent using measurement o...

extracts of cotoneaster medicus, glycyrrhiza glabra, as endemic plants of iran, along with mixture of them were investigated for their antioxidant activities using 2, 2- diphenyl-1-picrylhidrazyl (dpph) reagent. uv-vis spectrophotometry method was used to evaluate the ability of cotoneaster and glycyrrhiza glabra antioxidant to scavenge dpph radical. the kinetic parameters such as rate constant...
